Despite their robustness, fiber networks can fail due to: Physical Damage : Cuts, bends, or contamination in fiber cables or connectors. Hardware Failures : Faulty transceivers, switches, or routers. This guide offers practical steps to troubleshoot fiber optic cable issues, covering common problems, key tools, and preventive measures to ensure stable performance. The most common problems usually fall into four categories: Physical Layer: Transmission Performance: Equipment and Module Failures:. This thesis addresses these challenges through the development of machine learning and generative modelling techniques for anomaly detection and root cause analysis in cable broadband networks. With their ability to transmit data at speeds up to 1. 2Tbps over thousands of kilometers, fiber optics have outperformed. Consequently, it is imperative to develop an automated and reliable algorithm that utilizes telemetry data acquired from Optical Time-Domain Reflectometers (OTDR) to enable real-time fault detection and diagnosis in optical fibers. When issues like signal loss, slow speeds, or intermittent connectivity arise, systematic troubleshooting is key.
